Santa Fe looks to expand rebates for water-saving efforts

Israel has grappled with crippling drought for years. But people have learned to use Mediterranean sea water and recycled wastewater to provide the country with enough water for all its needs.

Low-income students are always looking for ways to finance their education. A new system using “human capital contracts” to pay for higher education isn’t as scary as it sounds.

54 million people in the United States, and 4.5 billion globally, have no credit to their name - making it nearly impossible for them to buy homes, apply for jobs and receive loans. Investors and lenders make an effort to help those with 'invisible credit' scores in financing essentials like homes or cars.

After the drought hit Australia in the early 2000s, city officials had to start thinking seriously about ways to conserve and creatively store their water. External tanks became the solution, storing rain runoff to create an available source of water for Melbourne residents. This solution may not fit every location, but there are other teachable lessons such as taking radically shorter showers.

Laws in Texas and New Mexico, both locked in the grip of a crippling drought, don't do much to actually encourage citizens to conserve water. New conservation laws and financial incentives are trying to change that.

Corporations concerned about their social and environmental impact must also consider the costs. Bcorps, a new form of corporation in the U.S., are using a rigorous certification process to gain consumers trust and boost sales.

Government benefits to aid the poor are frequently left unclaimed, leaving children hungry, young people unable to finish school, and opportunities for stable housing and preventative health care unused. New York City-based program Single Stop connects people to benefits for which they may be eligible. Importantly, Single Stop has served community colleges where disadvantaged students can use the assistance to help get through school.

New York City black tar roofs cause a number of environmental problems, including air pollution, heat absorption that raises energy consumption, and storm water runoff in the sewer system. Efforts to turn these old roofs into green spaces cool the buildings, enable the containment of more rainfall, reduce sewer discharge, generate energy, and absorb carbon emissions. New York City has a pilot program offering financial help for green roofs.

Clean water and healthy ecosystems are becoming increasingly difficult to come by. With floating islands and other inventions, eco-entrepreneur Bruce Kania thinks that biomimicry - such as reconstructing wetlands and growing biofilms - can tackle the toughest of water problems.

This is a column on an important new development program in use in at least 40 developing countries: give the poor cash payments, contingent on their use of health clinics and their children’s school attendance, to help break the cycle of poverty.
